摘　　要：运用三维直角坐标转换,先求出盾构机轴线局部坐标系与实际三维空间坐标系两种坐标系的转换参数,然后再利用转换参数求出盾首中心和盾尾中心点的实际坐标,进而计算盾构机的姿态,该方法用于地铁盾构的引导测量,取得了令人满意的效果。The paper applies the three-dimensional rectangular coordinate transformation to obtain the transformational parameter between two coordinate systems,that is,the axial local coordinate system and the factual three dimensional space coordinate system,than gets the factual coordinate of the shielding head center and the shielding tail center by the transformation parameter,and calculates the gesture of the shielding machine,and indicates the guidance measurement of the subway shielding,so as to have the satisfactory effect.

关 键 词：三维直角坐标转换 六参数 盾构引导
